The Federal Deposit Insurance Corporation Board is considering a proposed rule to modify the enhanced supplementary leverage ratio (eSLR) for US global systemically important banks (GSIBs), replacing the existing eSLR standards with a buffer linked to each firm’s GSIB capital surcharge. Under the proposal, the new buffer would equal 50 percent of a GSIB’s capital surcharge calculated under method 1 of the Federal Reserve’s GSIB surcharge framework and would apply at both the holding company and bank subsidiary levels. The FDIC estimates the change would reduce aggregate required Tier 1 capital at the holding company level by approximately USD 13 billion, or about 1.4%, and is intended to reduce leverage-driven constraints on low-risk activities such as US Treasury market intermediation. Acting Chairman Travis Hill indicated the FDIC will review public comments on the proposal.
